[QUESTION] Clang as QEMU compiler - two questions

[QUESTION] Clang as QEMU compiler - two questions

[Aleksandar Markovic]

Hello, all

I have two questions:

1) Is ./configure --cc=clang the correct way to enable clang
compilation of QEMU? Any other gotchas?

2) Did somebody compare QEMU compiled by gcc vs. QEMU compiled with
clang (in any sense: executable size, performance, etc.)?

Thanks in advance,
Aleksandar

You'll also want "--cxx=clang++", so the (few) C++ parts of
QEMU get compiled with the same toolchain.

It should just work -- clang is our default compiler for OSX
and is included in the CI and pre-merge tests on Linux.
